All you gotta do is multiply the cm by 15,
For 13) you'd do 2.5*15
14) 0.2*15 
15) 15*15
then for 16) 4.6*15

Let

x-------> distance in the map in cm

y-------> actual distance in Km

we know that

Scale\ Map=\frac{x}{y} \\ \\ Scale\ Map=\frac{1}{15}\frac{cm}{Km}

so

\frac{x}{y}=\frac{1}{15}

y=15x --------> equation 1

<u>Part 13)</u> find the actual distance corresponding to the scale map 2.5\ cm

In this problem we have

x=2.5\ cm

Substitute the value of x in the equation  1 to find the actual distance

y=15*2.5=37.5\ Km

therefore

<u>the answer part 13) is</u>

the actual distance is 37.5\ Km

<u>Part 14)</u> find the actual distance corresponding to the scale map 0.2\ cm

In this problem we have

x=0.2\ cm

Substitute the value of x in the equation  1 to find the actual distance

y=15*0.2=3\ Km

therefore

<u>the answer part 14) is</u>

the actual distance is 3\ Km

<u>Part 15)</u> find the actual distance corresponding to the scale map 15\ cm

In this problem we have

x=15\ cm

Substitute the value of x in the equation  1 to find the actual distance

y=15*15=225\ Km

therefore

<u>the answer part 15) is</u>

the actual distance is 225\ Km

<u>Part 16)</u> find the actual distance corresponding to the scale map 4.6\ cm

In this problem we have

x=4.6\ cm

Substitute the value of x in the equation  1 to find the actual distance

y=15*4.6=69\ Km

therefore

<u>the answer part 16</u>

the actual distance is 69\ Km

What is the inverse of the function f(x) = 2x - 10?
love history [14]
F(x)=2x-10

y=2x-10

x=2y-10

x+10=2y-10+10 (add both sides by 10)

2y=x+10

2y/2=x+10/2 (divide both sides by 2)

y=1/2x+5

Final Answer: f^-1(x)=1/2x+5

Evaluate. -|-7 + 3| <br> 4<br> -4<br> -10
agasfer [191]
Your answer is 4

You have to use the distribute property and distribute the - to the -7 and the 3

The -7 will become and the 3 will become -3

Then you add those together and when you add a negative to a positive you basically subtract

So 7+-3 is 4

A is your answer
